How to create suppression for BFCM

I want to clean my audience by following this instruction

• Build a segment to identify profiles who have soft bounced 5 or more times in the last 120 days.
• Build a segment to identify profiles who have opted in at least 180 days ago, but have not clicked or opened an email in the last 72 weeks.
• Build a segment to identify profiles who opted in for emails at least 180 days ago, but have not been active on site, added to cart, or placed an order in the last 72 weeks.

I’m unsure how to identify profiles who have opted in at least 180 days ago. What conditions should I set up when creating a segment for this? Additionally, I don’t have an ‘added to cart’ option available for segmentation. What alternative should I use instead?
